Bone anchor assemblies and methods are provided having a multi-component bone anchor that is configured to allow the shank of the bone anchor to be bottom loaded into a receiver member. In one embodiment, a bone anchor assembly is provided having a shank with a distal threaded portion and a proximal head portion, a ball having a spherical exterior surface and a central lumen sized to receive the head portion of the shank, and a clip configured to be engaged between the head portion and the ball such that the clip is effective to lock the ball in engagement with the shank.

Bottom-loading bone anchor assemblies and methods

Bone anchor assemblies are disclosed herein and include bone anchors, receiver members, and closure mechanisms. In one embodiment, a receiver member can be configured to seat a portion of a bone anchor and to receive a spinal fixation element, such as a rod. In an exemplary embodiment, the receiver member is bottom-loading and can include a seat having an opening that can be selectively increased and decreased in size so as to allow a bone anchor to be bottom-loaded. A force can be applied to the receiver member to increase a size of the opening, allowing a portion of the anchor to pass through the opening and into the seat. A closure element can be coupled to the receiver member and can apply a force to decrease a size of the seat and a size of the opening, angularly fixing the receiver member relative to the bone anchor.

Bottom-loading bone anchor assemblies

The present invention relates to a spacer, such as a polymeric spacer, for use with an implant device, e.g., a bone plate, for splinting a fracture of a bone. The spacer includes a body defining a bone healing surface, wherein at least a portion of the bone healing surface has a coating which includes a therapeutic agent, a polymeric carrier, and a buffer medium to stimulate bone growth and/or promote fracture healing. A kit is also disclosed which includes one or more of the spacers, at least one bone plate, and optionally one or more bone screws for securing the bone plate to bone. A method for promoting fracture healing in bone is further disclosed which includes securely situating a coated portion of the spacer adjacent bone.
